 I wonder what would be a good deprecation schedule.


I'd like to know something about the deprecation schedule of compiler features
too, that is when they will be removed from the DMD front-end. Things like part
of the complex number syntax, typedef, floating point comparison operators (are
they present still?), scoped classes, delete, implicit string joining, old
operator overloading scheme, and so on and on.

This stuff makes the front end code longer, may cause bugs (because you don't
have bugs in code that is not present), needs maintenance to be kept working as
DMD changes, makes the creation of alternative D compilers unnecessarily a bit
harder and laborious, and it may confuse newbies.

I've seen lot of talking about deprecated features (like the long discussion
about deprecation of delete), but only very rarely I've seen them actually
removed... (I remember the array[new], some bad C syntax removed recently and
what else?).

Bye,
